only.Expand description
Recognizes a case insensitive pattern.
The input data will be compared to the tag combinator’s argument and will return the part of the input that matches the argument with no regard to case.
§Example
use nom::bytes::streaming::tag_no_case;
fn parser(s: &str) -> IResult<&str, &str> {
tag_no_case("hello")(s)
}
assert_eq!(parser("Hello, World!"), Ok((", World!", "Hello")));
assert_eq!(parser("hello, World!"), Ok((", World!", "hello")));
assert_eq!(parser("HeLlO, World!"), Ok((", World!", "HeLlO")));
assert_eq!(parser("Something"), Err(Err::Error(Error::new("Something", ErrorKind::Tag))));
assert_eq!(parser(""), Err(Err::Incomplete(Needed::new(5))));
